Io Drawing. Application fled Illovembcr Heretofore the problem .ofremoving tires from the wheels of-motor vehiclesthas been troublesomeand causedconsiderable difli- ;culty in that after a tire has been onthe 'rim for a long period of time-it invariably sticks to the 1'1II1 toa greater or-lesser 'de-- --gree under difierent-conditions andcircumstances, due mainly to corrosion of the metal rim anddeterioration of the rubber and fabric materials in .the tire.These'tenden'cies' for the; tire to stick to the rim-cause considerabletrouble to the motorist especially when it is necessary to change 'atire while on the road without the aid of the inost effective tools. Infact, it is not infrequent that atire has become so frozen to the rim Pthat .it is necessary to injure the tire in order to remove it. i v

p The primary purpose of the present invention is to provide a newprocess of treat- -.applying a novel composition or' compound lion'thepurpose ofpreventing thetire from {sticking to the rim andto facilitateremoval 7 of thctire.

To-this end :I have provided a composition which may be used in anypracticable form, that is;-asf asolid in bar form to be carried in thecar or for quick and handy use in a garage by rubbing it onto the ,and'y' stirring. This composition when applied togthe metal rim. preventscorrosion to new or old (corroded) rims. In the latter 7 45, instanceafter all loose'rust has been brushed off the composition penetratesand, provides a coating over the adhering rust soas, to"

prevent further corrosion and likewise pro-. videa substantiallypermanent lubricant between the rim and tire which facilitates easyseparation of these parts. 7

My invention also contemplates the use of a fil er to give greater bodyto the composition; and to thise'nd I prefer to use a granular orpowdered soapstone or mica, or both. The proportions of theseingredients might vary considerably according th the particul ar form inwhich thecomposition is to be 7 used or to the condltlo'r'is or.requirements ofuse. One example, by weight, is beeswax and soapstoneone-haif part. Another is, beeswax one part, soapstone two parts, and Jnncain powdered form one-half part.

One of the important advantages of'my one part; graphite one andone-half parts,

invention is that the composition will not I deteriorate the rubberor'fabric material in the't-ire. In this regard it should be noted.

,thatjbeeswax is one of the principal constituents of. the composition,and that no petrolatum products or others are used which.

are injurious to rubber. Another advantage f'of my composition is thatit will not be af fected by weather conditions. I claim as my invention:
